Description

System for predicting life time of grinding roller of heddles polishing device}

The present invention relates to a polishing roll life prediction system of a heald polishing device, and more particularly, to abrasion of the polishing roll of a heald polishing device so that the wear of the polishing roll can be sensed using a proximity sensor formed in multiple stages. After that, it automatically adjusts the position of the polishing roll so that the polishing work is always performed in contact with the surface of the thin or punched heald, which is the material of the heald, and when the life of the polishing roll is over, The present invention relates to a polishing roll life prediction system of a heald grinding machine.

Generally, heald is a tool for opening movement, which is the three main movements of the loom, also called 'inga', and is a component of the loom that enables weaving by smoothly supplying wefts between inclined hundreds and thousands. Among them, the general heald form is formed by injection molding a stainless steel sheet in a long length so that the shape is symmetrical, and the width gradually decreases from the edge to the center.

On both edges of the heald, a fixing part for fastening with the heald frame is formed, and a body is formed inside the fastening hole, and the fixing part has a long hole shape so as to be fastened with the heald frame of the loom. The fastening hole is formed, the central portion of the body to form a heald eye to receive the passage through the inclination.

The heald is formed by using a plurality of healds fixed to heald framing in a state where a fixed bar is inserted into the fixing hole. It forms an inclined opening according to the movement, and the weaving of the fabric is made by the weft yarn supplied through this inclined opening.

At this time, when weaving the fabric, if the surface of the heald is rough or the edge is sharp, the thread breaks. When weaving the fabric as described above, the heald surface is cut by a multi-stage process to prevent the yarn being broken. Through polishing process, it is possible to remove surface polish of heald and sharpness of edge part.

Referring to the conventional heald polishing device as shown in Figure 1, by mounting a long injection molded thin plate made of stainless steel, which is the heald of the heald to a rotating roll formed on both sides to form a rotatable, A polishing process is formed on the upper surface of the thin plate to rotate in the opposite direction in contact with the polishing roll, and a support spring is formed below the surface of the thin plate so that the thin plate and the polishing roll can be in airtight contact. It is configured to prevent the thin plate from bending.

The polishing roll of the heald polisher is formed of a multi-stage polishing roll according to the degree of surface roughness so that the thin plate, which is the material of the heald, can be improved in the surface beauty through the multi-stage polishing roll and the sharpness of the edge portion can be removed step by step. The multi-stage polishing rolls are provided with lifting handles so that the polishing rolls can be lifted up and down.

In addition, in the case of stainless steel heald is manufactured by a punching operation, sharp burrs are formed at the edges of the cut portions and the holes such as heald eyes, fixing holes, etc., when removing the burrs generated by the punching of the heald. Edo polishing is performed by using a polishing apparatus having a multi-stage polishing roll.

The conventional polishing apparatus can be polished step by step using a multi-stage polishing roll according to the degree of surface roughness to improve the surface beauty and to remove the grime due to the sharpness or punching of the edges step by step. On the other hand, when a certain time elapses, the abrasive roll is worn out, and the abrasive roll is separated from the surface of the heald by the thin plate or the punching work, which is the material of the heald, and each time the operator manually removes the abrasive roll. Lower the surface of the polishing roll and thin plate or heald to make polishing work continuously.The worker cannot know exactly how the polishing roll is worn out and must pay attention at all times. There is a problem that the efficiency is lowered.

In addition, the lowering of the polishing roll by manual operation of the operator prevents the surface of the polishing roll and the thin plate or heald from being in proper contact, and thus the thin plate or the heald is bent, resulting in a decrease in surface beauty and no uniformity due to the manual operation. As a result, the defective rate increases, and even when the life of the polishing roll is not suitable for the polishing operation, it is impossible to detect the exact replacement time quickly, thereby reducing the work efficiency and shortening the service life of the polishing roll or heald. There is this.

The present invention has been made in order to solve the above conventional problems, by using a proximity sensor formed in multiple stages to detect the degree of wear due to the polishing operation of the polishing roll, and automatically controlled to operate as much as the polishing roll worn down. Therefore, the polishing operation is always performed while the polishing roll is in contact with the surface of thin or punched heald, which reduces the defective rate. The purpose is to detect and inform the outside worker.

Polishing roll which is driven by a rotary motor to perform the polishing action to achieve the above object; A rotating roller formed on both sides of the polishing roll and mounted with a thin plate which is a material of heald, and the thin plate rotating while being in contact with the polishing roll; A support spring formed to support the lower side of the thin plate to prevent the thin plate from being bent by the polishing roll; Proximity sensor unit is formed in the lower portion of the polishing roll to detect the position information spaced apart from the polishing roll, respectively; Polishing roll life predicting means for controlling the driving motor unit by the driving motor through the signal value transmitted through the proximity sensor unit to control the lifting roll, and to output the warning light, alarm sound according to the replacement time and polishing degree of the polishing roll; A heald grinding device comprising: a drive motor that is rotated in a forward or reverse rotation by receiving a control signal and a ball motor coupled to the polishing roll to move the polishing roll up and down by a rotational force of the driving motor; When the OFF signal value is input from the last proximity sensor of the proximity sensor unit formed in multiple stages, the alarm sound is output by predicting the life of the polishing roll, but using an operation key formed outside the life expectancy of the polishing roll. It is intended to implement a polishing roll life prediction system of a heald grinding apparatus including a life prediction setting unit that sets the life prediction step separately according to the polishing roll.
